The safety escape chute apparatus uses a rope which allows a user to escape and fall down to the ground or the other persons to do so. Also, the safety escape chute apparatus is so compact in volume that it is easy to keep it in custody and carry it. Anyone can use the safety escape chute apparatus safely and simply.

TECHNICAL FIELD

The present invention relates to a safety escape chute apparatus, and more particularly to, a safety escape chute apparatus for rescuing people using a rope.

BACKGROUND ART

In general, when a disaster takes place, ropes are used to rescue people to escape from a high position to a low position. For example, in the case of a high building where a fire broke out, some people who can escape using ropes can escape from the firing building using ropes, and the others who cannot escape using ropes should escape under the assistance of the other people.

Also, people who escape using ropes are classified into one who can escape alone using ropes and the others who should escape under the assistance of the other people.

People who can escape alone using a rope should firmly bind up one end of the rope at an escape position and take the hold of the rope to then descend slowly. However, people who should escape using a rope under the assistance of the other people, should firmly bind up one end of the rope at the waist of the other people and take the hold of the other end of the rope to then descend slowly when the other people releases the rope slowly.

As described above, it is possible to escape using a rope from a danger place but it is still dangerous. That is, if a people who escapes drops a rope or for a people who supports the rope drops the end of the rope, a danger still remains. Thus, it is desirable to provide a safety escape chute apparatus that does not cause any danger even if users drop the rope.

Since the above-described ropes and safety escape chute apparatus are essentially needed but are not frequently used, the following requirements should be satisfied. First, the safety escape chute apparatus should be used for people's escape. Second, the safety escape chute apparatus should be compact in volume so as to be easily kept in custody. Third, the safety escape chute apparatus should be safely used. Fourth, anyone should be able to use the safety escape chute apparatus.

However, currently available safety rescue equipment is so large to be difficult to move it. Also, compactly designed rescue equipment is designed to rescue only a user who uses it. Also, a safety escape chute apparatus that is registered as Utility Model Registration No. 0148216 on Mar. 15, 1999 to the same inventor as that of the present invention, is designed to rescue a user in question and the other persons as in the present invention. But, since a brake and regulation unit of the safety escape chute apparatus is made in the form of a vice that is controlled by rotating a handle thereof, a beginner or an old and feeble person has the difficulty in steering the handle at the psychologically unstable state due to a falling fast speed. Also, it can be seen from an experimental process that a preliminary training about how to use the safety escape chute apparatus is considerably required. Thus, to solve the above problems, it has been required that a safety escape chute apparatus should allow users to manipulate braking and regulation more speedily, easily and safer.

DISCLOSURE OF THE INVENTION

To solve the above problems, it is an object of the present invention to provide a safety escape chute apparatus using a rope which allows a user to escape and fall down to the ground or the other persons to do so.

It is another object of the present invention to provide a safety escape chute apparatus which is so compact in volume that it is easy to keep it in custody and carry it and which can be used by anyone safely and simply.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinbelow, a safety escape chute apparatus according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a state of using a safety escape chute apparatus according to the present invention.

Referring to FIG. 1, a second case 3 containing a rope length fixing control unit which is installed in a main body 1 in which a rope 20 is installed, for selectively controlling a length of the rope 20, is made of cast-iron steel. Also, a first case 2 containing a rope release regulation unit which is spaced from the second case 3 containing the rope length fixing unit and is installed in the main body 1 in order to control a release of the rope 20, is made of cast-iron steel. Also, a ring 4 which is connected to a hanger 29 in a safety belt 28 shown in FIG. 5 showing that a user wears the safety belt 28 during escape, and is fixed to the body of a user during escape, is fixed to the main body 1.

FIG. 2 is a side sectional view showing a state where a rope, a control plate and a lever are installed in the safety escape chute apparatus shown in FIG. 1.

Referring to FIGS. 1 and 2, the rope release regulation unit includes a first case 2, a first control plate 10, a first control plate support axis 12, a first control plate connection regulation lever 7, a first control plate regulation handle 6, a first control plate handle frame 5, and a spring 8.

In the rope release regulation unit, the first case 2 is formed of cast-iron steel in the main body 1. The first control plate 10 whose one end portion is screw-connected with a slide bar control plate support axis 12 whose one end portion is formed with a screw is connected on the upper end of one side of the first case 2. The first control plate regulation lever 7 whose one end portion is screw-connected on a screw axis 12 with the first control plate 10. The first control plate handle 6 is connected with the regulation lever 7 by the screw pin 15 in order to operate the regulation lever 7. Also, the control plate lever 7 is connected with the first control plate handle 5 which is connected with the handle 6 by a screw pin 16 and is connected with the first and second cases 2 and 3 by each screw 21, in which a spring 8 is elastically supported between the handle frame 5 and the handle 6.

Referring to FIG. 1, an elongate groove 23 is formed in the inner side of the first case 2 so that the connection lever 7 can freely function. The handle frame 5 is connected to the first and second cases 2 and 3 by each screw 21 in an arched shape. Also, a first passing hole 17 is formed in the first case 2, through which the rope 20 can pass.

FIG. 3 is a front perspective view of a first control plate shown in FIG. 2.

Referring to FIG. 3, an up-and-down elongate groove 26 is formed in the central portion of the first control plate 10, so that the first control plate 10 can move up and down. The lever 7 is installed in the elongate grove 26 by a lever support pin 15.

Referring to FIGS. 1 and 2, the rope length fixing unit includes a second case 3, a second control plate 11, a second control plate connection slide bar support axis 13, a handle 14, and a spring 9.

In the rope length fixing unit, the second case 3 is formed of cast-iron steel in the main body 1. The second control plate 11 is screw-connected with the slide bar control plate support axis 13 in the upper end of one side of the second case 3. The handle 14 is installed in the lower end of one side of the second control plate 11 which makes the second control plate 11 move forward and backward. The spring 9 for elastically restoring the second control plate 11 is screw-connected on the central portion of the second control plate 11. The path 18 is formed in the form of an elongate groove and in an arched shape on one side of the handle 14 in the second case 3, to thereby provide a reciprocating path for the handle 14 so that the handle 14 can move up and down when the rope 20 is installed or fixed in length. Also, the handle 14 is twisted at a 45° angle or restored into an original position so that the handle 14 can freely stop and release at a point where the handle 14 need to operate.

The second control plate 11 is screw-connected in the second case 3, by the slide bar control plate support axis 13 passing through a second control plate support axis passing hole 22 which is formed in the upper end of one side of the second control plate 11, with a screw formed in the end of the slide bar control plate support axis 13. The handle 14 is screw-connected on the lower end of one side of the second control plate 11. The spring 9 is screw-connected in the central portion of the second control plate 11. When a user takes the hold of the handle 14 and then pushes up it through the reciprocating path 18, a gap is formed between the bottom plate of the main body 1 and the second control plate 11. Accordingly, a rope 20 is inserted into a second passing hole 25 to then be installed in the main body 1. Also, when a user ties up the rope 20 at a fixing position where the rope 20 can be firmly tied up, and then releases the pushed handle 14 after securing a desired length of the rope 20, the second control plate 11 is moved together with the rope 20, by an elastic restoring force of the spring 9 and a releasing force of the rope 20. Accordingly, a gap is gradually narrowed between the bottom plate of the main body 1 and the second control plate 11, and then the rope 20 brakes. Then, when the handle 14 is twisted at 45° after the rope 20 has completely braked, the rope 20 is more stably fixed together with the second control plate 11. The second passing hole 25 is formed in the second case 3 in lengthy direction of the main body 1 so that the rope 20 can pass through.

The safety escape chute apparatus using the rope 20 having the above-described structure can be used to make a user to escape and fall down to the ground or the other persons to do so, as follows.

Referring to FIG. 2, when the handle 6 is pulled toward the handle frame 5, the first control plate 10 is pulled upward through the connection lever 7, and a gap is formed between the main body 1 and the first control plate 10 so that the rope 20 can sufficiently pass through.

Referring also to FIGS. 2 and 4, when the handle 14 attached on the second control plate 11 is pulled toward the spring 9, a gap is formed between the second control plate 11 and the bottom plate of the main body 1, so that the rope 20 can pass through. Then, the rope 20 is inserted into the first passing hole 17 and the second passing hole 25 with the gaps, and thus installed at a state where it is used for escape.

Then, referring back to FIGS. 1 and 2, in order to rescue the other persons, one end of the rope 20 toward the second case 3 is tied up at a firm position. When the second control plate handle 14 is pushed up along the arched handle reciprocating path 18, the second control plate 11 is raised and thus a sufficient gap is formed between the second control plate 11 and the bottom plate of the main body 1 to thereby allow the rope 20 to freely move. Here, when the length of the rope 20 is regulated at a proper position such as a window, and then the handle 14 is released, a gap is narrowed between the second control plate 11 and the bottom plate of the main body 1, by an elastic restoring force of the second control plate spring 9 and a force which the rope 20 pulls forward. Thus, a certain pressure is applied to the rope 20 to thus brake the rope 20.

Then, the end of the rope 20 toward the first case 2 is hung up a hanger 29 of a safety belt 28 shown in FIG. 5 which is worn around the waist of the other person to then make the rope 20 descend. In this case, when a rescuer looks at the other person and takes the hold of or releases the handle 6, the rope 20 is properly released to regulate a descending speed. As a result, a person to be rescued can safely descend.

Meanwhile, when a user wants to escape along, the handle 14 in the second case 3 is raised and then the handle 14 is twisted at an angle of 45° and fixed. In this case, the second control plate 11 is fixed at the raised state, and thus the rope 20 fitted between the second control plate 11 and the bottom plate of the main body 1 becomes free. Then, the user makes the rope 20 drop down to the ground toward the second case 3 and lined up in a single straight line. Then, the end of the rope 20 toward the first case 2 is tied up at a firm place, and then the hanger 29 of the safety belt 28 shown in FIG. 5 and worn at the waist of the user is hung up the ring 4 fixed to the main body 1. Accordingly, when the user takes the hold of or releases the handle 6 properly, he or she can regulate a descending speed and escape safely down to the ground.

The safety escape chute apparatus according to the above-described embodiment of the present invention is nothing but an embodiment. One skilled in the art who sufficiently understands the preferred embodiment of the present invention can realize a safety escape chute apparatus in various forms.
